Master Sgt. Dennis Griffith, 28th Civil Engineer Squadron NCO in-charge of readiness, ensures the mobile emergency operations center trailer connects properly to an emergency management vehicle here, March 12. Part of the objective for the exercise was to determine a timeframe for the EM flight to depart the installation and travel to Rapid City Regional Airport in order to support civil authorities in the case of a natural or manmade disaster. Ellsworth Airmen teamed up with their civilian counterparts during the exercise, in an effort to develop a working relationship and become familiar with the policies and procedures of each other.
